Railway Screw Spikes - Technical Specifications & Features
This table outlines the basic specifications, advantages, and disadvantages of screw spikes themselves.
| Aspect | Description |
|---|---|
| Basic Definition | A threaded fastener used to secure rails to wooden or composite sleepers (ties) by being rotated into a pre-drilled hole. |
| Primary Function | To provide a strong, mechanical lock between the rail base and the sleeper. |
| Key Components | • Spike Body: The main threaded shaft. • Head: Typically a square or hexagonal head for tool engagement. |
| Common Materials | • Medium Carbon Steel • Alloy Steel (for higher strength requirements) |
| Surface Treatment | • Hot-Dip Galvanizing (most common for corrosion resistance) • Black (untreated, for indoor or temporary use) |
| Key Advantages | • Superior Holding Power: Resists pull-out and lateral forces better than driven spikes. • Reduced Sleeper Damage: Minimizes splitting of wooden sleepers. • Reusability: Can often be unscrewed and reused. • Ease of Removal: Simplifies track maintenance. |
| Key Disadvantages | • Higher Initial Cost: More expensive than cut spikes. • Slower Installation: Requires drilling and screwing. • Requires Special Equipment: Needs dedicated drilling/spiking machines or powerful impact wrenches. |
Screw Spikes vs. Cut Spikes - A Comparative Analysis
This table provides a direct comparison between screw spikes and the traditional cut (drive) spikes across critical parameters.
| Parameter | Screw Spike | Cut Spike (Traditional) |
|---|---|---|
| Fastening Principle | Threaded engagement via rotation. | Friction and deformation via impact driving. |
| Holding Power | Very High. Superior long-term resistance to loosening under dynamic loads. | Moderate. Can work loose over time due to vibration and wood shrinkage. |
| Impact on Sleeper | Low. Minimizes splitting and internal damage, extending sleeper life. | High. Can cause splitting, crushing, and degradation of wood fibers. |
| Reusability | Good. Can typically be unscrewed and reused multiple times. | Poor. Often bent or deformed during removal; holding power is significantly reduced if reused. |
| Initial Cost | Higher (component + installation). | Lower. |
| Maintenance | Easier for targeted removal and replacement. | Often requires driving new spikes into new locations on the sleeper. |
